Microsoft Windows PC is free software that offers an extra line of defence against malicious and spyware software. Windows Defender scans the PC’s hard drive to search and eliminate a range of security threats, including viruses, spyware, and malicious software also known as malware. By removing these viruses, threats, Windows Defender speeds up the performance of the device and also avoids annoying pop-up ads that can ruin your experience of web browsing.
Other antispyware and spyware software has started annoying. Due to better competition, each antispyware is trying to outdo each other by not allowing others to run.
Windows could not start the Service of Windows Defender on the device
Windows cannot verify the digital signature for the folder or file. Recent software or hardware changes may have installed a file that is damaged or signed incorrectly from the unknown source.
The reason is that the value of the registry has been changed to disable turning on Windows Defender and your antispyware is the most likely cause. Follow these steps:
- First, uninstall any other antispyware or antivirus you might have installed like Spybot Plus, Avast, Norton, McAfee, Comcast Complete Protection, etc.
- Restart your device.
- Go to regedit.exe and navigate to HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft-Windows Defender.
- You need to change it to 0 (zero) by having a right click and then changing and modify value data. If you are not able to change the value, you will have to restart it in safe mode.
- Restart your device.
- Now go to Action Center or Windows Defender app and you would be able to turn on Windows Defender.
